Question 62273
Given  1/y = 3/5 - 2/x

Leave the term which contains "x" and bring all the other term to the other side.

We have,

1/y - 3/5 = - 2 /x

MUltiply the above by "x", we get

 - 1/ y + 3 / 5 = 2 /x

Simplify the above, we get

- 5 + 3y / 5y = 2 / x

Cross multiply the terms, we get

 x ( -5 + 3y ) = 2 ( 5y)

 x ( -5 + 3y) = 10 y

 x = 10 y /  (-5 + 3y)

 The above solution will solve for "x"
